T at whom it may concern.-

Be it known that I, RICHMOND 1-I.'INGER- soLL, a citizen of the United States, residing March 14, 1882; No. 46l,613,dated October,

20, 1891; No. 468,914, dated February 16,

1892, and No. 590,008, dated September 14,

1897; and my invention consists in certain improvements in the mechanism for separat ing and holding the heddle-cords with their eyes in the path of the reciprocating needle, wherebyit is simplified and rendered more accurate and reliable in its operation; and my invention also consists in certain novel devices and combinations of parts, as hereinafter particularly set forth, in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a machine for drawing in warp-threads embodying my improvements, some of the warp-threads being shown broken off above the clamp. Fig. 2 is a transverse vertical section on the line 2 2 of Fig. 1. Fig. 3

and pointed out is an enlarged sectional plan of the heddlecord-separating mechanism, taken on the line 3 3 of Fig. 4. Fig. 4 is an end elevation of the same, the central portion being broken away. Fig. 5 is a rear elevation of the same. Fig. 6 is a side elevation of the same. Fig. 7 is an enlarged vertical section on the line 7 7 of Fig. 1, looking in the direction of the arrow. Fig. 8 is a perspective view of the beddle-cord-separating mechanism, the supporting standards and operating levers being broken away below the platforms. Fig. 9 is a perspective view of the heddle-cord-sepa rating devices, illustrating the manner in which they operate to release the heddle-cords in succession. Fig. 10 is a similar view with the parts in a different position. Fig. 11 is a View of the reverse or opposite side of the parts shown in Fig. 10, said parts being in the same position as in Fig. 10. i Fig. 12 is a third position.

Figs. 18 and 19 are perspective views of the wedge-shaped slides which act on the eyes of the heddle-cords to force them outward between the holdingjaws. Figs. 20 and 21 are perspectiveviews of the fingers which finally act upon the heddle-cords to force them' out from the separating mechanism. Fig. 22 is a perspective view of the front end of one of the platforms which support the heddle-cord-separating mechan- I ism. Fig. 23 is a perspective View of the separating-arm, its supporting-sleeve,and the cone-shaped spindle on the latter. Fig. 24: is ahorizontalsection on the line 24 24 of Fig. 23. Fig. 25 is a vertical'section on the line 25 25 of Fig. 23.

The framework of the machine may be of. any suitable construction and in the present instance consists of a bed A, which is supported on suitable'legs and is provided with guides, to which is adapted a traversing carriage onslide B, which is fed from right to left by means of a feed-screw O, drivenfrom the main or driving shaft D of the machine through the medium of suitable gearing and other connections. (Not shown.) The shaft D is provided with the ordinary fast and loose pulleys, as shown in Fig. 1.

Between vertical end pieces or standards I) b rising from the bed A are secured four horizontal tubular rods 0, upon which slide the hangers G, which support the hedd-les H I, the upper and lower bars of which fitwithin rectangular eyes or yokes' at the ends of said hangers. J, Figs. 3, 4, and 8, represents the reed-separating device, and K, Figs. 1 and 7, the reed, which is supported in a suitable frame secured to the standards I) b, and L is the warp-drawing needle, which is a flat steel bar pointed and barbed at its front end, said needle being reciprocated in a tubular casing d, mounted on a boX or casing M, secured to the front of the carriage B and being reciprocated by suitable mechanism, all of the above-described parts being constructed and operating in the manner fully described in my aforesaid Letters Patent No. 461,613.

The mechanism by which the warp-threads eare successively selected and carried one at a time against the barbed needle L into a position to insure their being caught by its hook f as the needle is retracted, so as to be drawn '15 thereby through the eye of the heddle and between the dents of the reed, is shown at the right-hand end of Figs. 3 and 4.

N is a standard which is bolted to the car:

riage B, Fig. 4, upon which is mounted a swinging curved arm 30, carrying at its outer end the selecting-hook g, by means of which the warp-threads are successively presented to the reciprocating warp-drawing needle L in a manner to insure each one being caught thereby in its turn.

P' represents a long bar having beveled edges, against which the warp-threads are tightly pressed when stretched between the upper and lower clamping devices of the warp- 0 holding frame, (not shown,) and Q is the thread-separating comb, having shallow vertical grooves for receiving the warp-threads. A hook h cooperates with the selecting-hook g, and both of these hooks are operated by,

5 suitable cams on a vertical shaft Y. This thread-selecting mechanism is substantially the same as that shown, described, and claimed in my aforesaid Letters Patent No. 590,008, and as it forms no part of my pres- 40 cut invention will not be herein further referred to.

R, Figs. 3 and 6, represents the horizontal vertically-reciprocating nippers which operate to take up the slack in the warp-threads 5 as they are presented to the selecting mechanism. These nippers are substantially similar in construction and mode of operation to those shown and described in my aforesaid patents, Nos. 461,613and 468,914, and as they form no part of my present inventionthey will not be herein further described.

The mechanism for separating the heddlecords and holding them with their eyes in the path of the reciprocating needle L in such 5 5 man-n er that the passage of the latter through the heddle-eyes will be insured will now be described, said mechanism forming the subject of my present invention and being shown particularly in Figs. 3 to 25, inclusive. The

operation to be effected is the same as in the machine described in my Patent No. 461,613, before referred to-that is to say, the needle passes first through the reed K, then through an eye :of the heddle H, then between two eyes of the heddle I, Fig. 8, and after receivin g a warp-thread 6 draws it between two eyes of the heddle I, through an eye of the heddle H, and through the reed; but on the next stroke the needle passes between two eyes of the heddle H and through an eye of the heddle I and receiving another warp-thread 6 draws it through an eye of the heddle I, between two eyes of the heddle H, through the reed, and so on until all of the warp-threads have been drawn through the heddle-eyes and the reed.

The number of threads which pass through each space between the dents of the reed corresponds to the number of heddles being threaded in the machine.

The eyes of each heddle are selected and separated one by one in properorder and held in position for the passage of the hooked needle L in the followingmanner, and as the eyeseparating mechanism for the heddle H is precisely like that for the heddle I, the two mechanisms being so connected with the power that the heddles are acted upon alternately, I will describe only the device for acting on one heddle, which will apply equally to the device for acting on the other heddle.

S S are two plates or platforms, which are supported on posts or standards T rising from the carriage B, and between these two platforms is a space or channel t', through which the heddle-cords pass as the carriage B, with the platforms S S, is traversed from one end of the machine to the other, this space being narrowed down toward the rear end, as seen in Figs. 3,14, and 15, toawidthjust sufficient to allow the passage of one of the eyes of the heddle-cords when said eye is turned edgewise, so as to face toward the front of the machine.

At the rear end of each of the platforms upper and lower jaws being just sufficient to hold a heddle-eye with its upper and lower knots fitting close up under the lower plates 7.: and down upon the upper plates m, as shown in Fig. 8, the distance between the two jaws of a pair being sufficient to allow the passage of a heddle-eye turned edgewi'se, so as to present a single thickness of the cord only, and with its face presented toward the front of the machine and directly in the path of the reciprocating needle L, which as it advances is held closely up against the vertical end faces 50 of the platforms S S.

At the corner of the platform S which is close to the front of the machine is placed a guide U, Fig. 8, through which the needle L passes, said guide being provided with a downwardly-extendingandinwardly-inclined flange 51, which serves to catch the point of theneedle in case it should have become accidentally sprung outward and carryit sn ugly against the end face of the platform.

The heddles are constructed in the usual manner, as shown in Figs. 9, 10, and 11, and between the cords of each heddle, above the eyes, passes a rock-shaft V, which is sup:

IlO

ported at its opposite ends in bearings 52 53,

are tapered or inclined to meet the thin edge of the arm W, thus forming wedges 40, the purpose of which will be presently explained. A flattened thin-edged bar 55 is, as usual, introduced longitudinally between the cords of the heddles and is suspended in any suitable manner for instance, by means of wires-at such a height as to bring it directly under the eyes of the heddle at a short distance therefrom, which will cause the face of each eye to be presented toward the front of the machine. From the upper' side of the sleeve 54 projects an arm 56, carrying at its upper end a short horizontal rod or spindle 57 parallel with the shaft V and cone-shaped at one end, as shown at 58. The function of this oscillating arm W and the cone-pointed rod 57, which cooperates therewith, is to sepa rate the heddle-cords and select eye after eye in succession to be subsequently presented to the needle by mechanism to be hereinafter de-. scribed. As the shaftV is rocked and the arm W and rod 57 swung or vibrated first to one side and then to the other the cone-shaped end 58 puts a tension on the heddle-cords lying in its path by its pressure thereon, as shown in Fig. 10, causing the cords of the eye inadvance on the side opposite to the direction of movement of the separating-arm to slide down to the point or end of thecone, thus separating them from those in the rear, as shown in Fig. 10, and as the separating-arm W reaches the limit of its vibration in that direction the thin end or point of the wedge-shaped end 40 of the lip n on that side rests against the knot or lower end of the eye of the next heddle on the opposite side, as shown particularly in Fig. 11, thus holding back all the heddles on that side. Now as soon as the arm W commences to swing back in the opposite direction the said Wedge-shaped end 40, acting against the knot or lower end of the contiguous heddle-eye, presses or wedges it back, thus stillfurther forcing back all of the beddle-cords on that side and insuring a sufficient separation between the heddle-cords of the eye last released and those of the eye next to come forward to render it certain that the separating-arm will pass between them. This lip 'n,with its wedgeshaped ends, thus renders the action of the separating-arm W absolutely perfect, as it prevents any possibility of its failing to pass properly between and separate the heddle-cords, and I therefore regard it as a very important feature of my invention.

work.

Iwillnow describe the connections between the driving-shaft and the two shafts V, whereby the latter are rocked to operate the two separating-arms W. To the driving-shaft D is secured a gear 60, Figs. 1 and 2, which meshes with a gear 61 on a short shaft 62, supported on a stud 63 and carrying a bevelgear 64, meshing with a bevel-gear 65 on a short vertical shaft supported in a bearing 66 and carrying at its upper end a bevelpinion 67, meshing with a bevel-gear 68 on a short horizontal shaft 69, supported in a bearing in the framework and carrying a gear 70, which meshes with an intermediate gear 71, the latter meshing with a gear 72 on a short shaft 73, supported in bearings in the frame- The shafts 69 73 each carrya camwheel 75, Figs. 1 and 7, within the groove 76 of which fits a cam-roll at the end of a vertical rod 77, which slides in suitable bearings projecting from the framework. To the upper end of each of the sliding rods 77 is pivoted a link 78, the upper end of which is connected by a pin and slot with an arm 79, se-

cured to an extension of the rock-shaft V, which is thus rocked at the proper times by the revolution of its cam-wheel 75.

The mechanism by which theoscillating separating-arm W is traversed along its shaft V in unison with the carriage B will now be described.

(1 q are two bifurcated carriers, each branch of which is provided at its outer end with an antifriction-roll 80, the two branches or arms of each carrier of a pair receiving between them the separating-arm W as it is swung over to one side or the other, said separatingarm being always between the branches of one or the other of the two carriers when swung to one side or between the branches of both carriers when in its central position, one of the arms W being shown in the latter position at the right-hand end of Fig. 3. The carriers are each secured to a slide 81, moving in a groove or way 82 in the table S or S, and hence the separating-arms W must traverse on their rock-shafts V with the tables S S, which latter are mounted on the carriage B, as previously described.

Each of the slides 81 is reciprocated to withdraw its carrier entirely out of the Way of the line of heddle-cords on that side by means of a lever 83, which enters an aperture St in the carrier, said lever being provided at its opposite end with acam-roll 85 and being actuated against the resistance of a spring 86 by a cam 87, fast on the upper end of a vertical shaft 88, at the lower end of which is a bevel-gear 89, Fig. 5, which meshes with a bevel-gear 90 on a horizontal shaft 91, carrying at one end a gear 92, which meshes with a gear 93, rotating on a stud 94:, Fig. 6, and having fastened to it a bevel-gear 95, which meshes'with a bevel-gear 96 on the end of an inclined shaft 97, Figs. 4 and 5, supported in a long bearing 98 and carrying at its opposite end abevelgear 99, meshing with a bevel-gear 100, rotating on a stud and having fastened to it a gear 101, meshing with a gear 102 on a long horizontal shaft 103, Figs. 3, 4, and 6, which carries a bevel-gear 104, meshing with and driven bya bevel-gear 105 on the upper end of a short vertical shaft 106, which receives motion from the driving-shaft of the machine through in-, termediate connections. (Not shown.)

A B, Figs. 18 and 19, are a pair of, double wedge shaped slides,which are guided in slots 108, Fig. 22, in the platformsS S and are reciprocated simultaneously in opposite directions by means of levers 109 110, connected thereto at 112, as shown in Fig. 4.." These shaft, as previously described.

levers 109 110, which are fulcrumed, respectively, at 113114, are coupled together by a curved connecting-rod .115, Fig. 4, and the lever 109 is provided with a cam-roll 116, which fits within a cam-groove 117 in the face position shown in Fig. 13, which I term the second position, so that the antifriction rolls at the ends of its two arms will be en tirely out of the way of the line of heddlecords on the left-hand side. The separatingarm W is now swung over to the right between the branches of the carrier (1 into the third poof a cam-wheel 118, fast on the shaft 103, which receives its motion from the driving- Each of the slides A B is composed of two members rs, spaced apart by means of a block or piece 25, to which they are attached, said block if fitting within the slot 108, and the slide having pivoted to its lower end the upper end of its operating-lever.

One side or face of each member of the slides A B is beveled or inclined, and the upper and lower inclined portions of the slide A are each mortised out, as shown at 119, to receive corresponding tongues u, forming the upper and lower inclined portions of the slide B, whereby as the two slides are closed together the heddle-cords will be caught between them and resting against their inclined sides will be forced outward to carry the heddle-eye between the jaws 7s m and the heddlecords of said eye against the inner sides of a pair of spring-pressed fingers 21 U to firmly hold the eye in the path of the needle L, as

shown in Fig. 16, and at the right-hand end of Fig. 3, said fingers 12 being pivoted at 120 121 to a slide a, Fig. 21, fitting within a slot 122, Figs. 3 and 12, in the platform S. The free ends of the two fingers 12 extend under and slightly beyond the inwardly-inclined ends a: of two unyielding fingers b b, secured reciprocation is given to the two pairs of fingers o b, and consequently'with the parts in the position shown in Fig. 16 as the fingers e b are moved from left to right after the heddle-eye has been threaded the beveled or inclined ends 00 of the fingers b will catch the heddle-cords of this eye and force them outsition, (shown 1n Fig. 14,) the separating-arm WV beingalso shown in the third position in Fig. 10, just previous to which the slides A B separate to allow of the passage between them of the heddle-cords of the eye just released. This movement of the separating-arm W releases the cords of the foremost heddle-eye on the left side, as shown in Fig. 14, the cone-shapedend of the rod 57 at the same time putting a tenin Fig. 10, and causing them to instantly separate from those of the heddle-eyes in the rear, when they will pass out beyond the points of the wedge-shaped slides A B, which now close together, causing the tongues u to enter the mortises 119, as shown in Fig. 15, which I term the fourth position, when the cooperatin g inclined or beveled sides of said slides, acting on the heddle-cords above and below the heddle-eye, will force or wedge the same outward into the fifth position, (shown in Fig. 16,) and during these movements the carrier q and the separating-arm W return to their original first positions, as shown in Fig. 12. The heddle-eye is now squarely between the jaws is m, in which position it is firmly held by the two fingers or, which press the heddle-cords of said eye against the opposite edges of the slides A B. The needle L now passes through the heddle-eye, receives a warp-thread, and draws it back through said eye, immediately after which the two pairs of fingers o I) move to the right,when the inclined ends as of the fingers b will contact with the heddle-cords and passing behind or on the inner side of the same force the heddle-eye outward and beyond the path of the needleL into the sixth or last position, (shown in Fig. 17,) the fingers o yielding during this movement to permit the cords of the threaded eye to pass freely out from between the ends of the opposite pairs of fingers, after which the heddleeye will pass entirely out of the jaws 7a m as the platforms S S are moved along with the traversing carriage B. The carrier q in its turn is drawn back out of the way of the row of heddle-cords on the right-hand side of the heddle II and the separating-arm 1V swung over to the left between the branches of the carrier q to release the cords of the foremost heddle-eye on the right-hand side, and the operation of the parts is then repeated, the slides A. B and fingers o b acting on the heddle-cords of this eye in the same manner as on the one last described. \Vhen the machine is arranged for threading two heddles, as in the present instance, the eyes of the rear heddle are all held out of the path of the needle whilea single eye of the front heddle is being threaded and the eyes of the front heddle are then held out of the way while an eye of the rear heddle is being threaded, these alternate actions being continued until all of the eyes of both heddles have been threaded. As soon as an eye of the front row or series of cords of the heddle H has been carried into position between the jaws m and while the needle is passing through said eye the front row or series of cords of the other heddle I is released by the movement of its separating-finger W, and the cords of the foremost eye of this series are permitted to pass forward into the narrow portion of the channel 1', and by the time that the eye of the heddle H has been threaded and pushed outward by the fingers 2; b the eye of the heddle I has arrived into the proper position between the jaws k m of its separating device for the passage of the needle therethrough, and while an eye of the heddle I is being threaded the separating-arm W of the heddle H remains stationary in its central position, as shown in Fig. 9, to hold back both series of cords, and as soon as the thread has been drawn through the eye of the heddle I and said eye has been pushed outward by its fingers 'u b, and while the needle is being drawn back to carry said thread through the reed, the separatin g-arm W of the heddle II releases the back series of cords of said heddle, the cords of the foremost eye of 'which are then carried forward, as previously described, and while this is taking place the separating-arm W of the heddle I remains stationary and holds back both series of cords of said heddle I, and in this manner the two separating devices operate alternately, a front eye of the heddle H being first acted on and threaded, then a front eye of the heddle I, then a back eye of the heddle H, and finally a back eye of the heddleI, these operations being'repeated until the eyes of all of the cords have been threaded.

The reed-dent separator J is driven from the shaft 103 by means of suitable connections (not shown) and operates in the same manner as described in my aforesaid Patent No. 461,613, said separator making a single revolution immediately after the needle has drawn the required number of Warp-threads through a single space between the dents of the reed.

Ina machine for drawing 'in warpthreads, the combination with the traversing carriage, the reciprocating warp-drawing needle and the platforms mounted on the said carriage, and having a space or channel between them, and the eye-holding jaws at the end of said channel, of the oscillating heddle-cord-separating arm, the reciprocating carriers for receiving said arm and traversing the same, means for alternately withdrawing said carriers out of the way of the heddlecords, the wedge-shaped slides moving simultaneously in opposite directions, and adapted when closing together, to engage the heddleeye between them, and force it outward into the path of the needle, and the oppositely arranged pairs of fingers for holding the heddle-eye against the outer edges of the Wedgeshaped slides and in the path of the needle while being threaded, and subsequently forcing said eye out of the path of the needle, and holding it at the ends of the jaws while the wedge-shaped slides are being drawn back, and means for actuating said slides and fingers, substantially as described.

12. In a machine for drawing in warpthreads,the combination of the oscillating and traversing heddle-eye-separating arm and its bifurcated reciprocating carriers, the recip- 'rocating wedge-shaped slides adapted when closing together, to engage the heddle-eye between them, and carry it outward into the path of the needle, and the two oppositelyarranged pairs of reciprocating fingers coupled together to move simultaneously in the same direction, one pair of said fingers operating to hold the heddle-eye against the wedgeshaped slides while the needle is passing through said eye, and the opposite pair of fingers havinginwardly-inclined pointed ends adapted to pass behind the heddle-eye, and force the same to the outer ends of the eyeholding jaws, and hold it in position during the withdrawal of the wedge-shaped slides, substantially as described.
